no ALL WHOM IT MAY concerns;

Be it known that I, AARON ARMSTRONG, of Gillespie, in the county ofMucoupin, and State of Illinois,

have invented a new and improved Corn-Planter; and I do hereby declarethat the following is a full, clear, kc and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon.

This invention relates to a new and improved cornvplanter of that classwhich is mounted on wheels, and on which the driver rides.

The invention relates to a new and improved mode of raising thefurrow-shares Out 0 an improved mechanism for operating theseed-distributing device.

In the accompanying sheet of drawings- Figure 1 is'a side sectional viewof my invention, taken in the line a: :v, fig. 2. 1

Figure 2, a plan or top view of the same.

Figure 3, a transverse vertical section of the same, taken in the line'yy, fig. 2.

Similar letters of reference indicate like parts.

A represents the frame of the machine, which is supported, atits rearpart, by two wheels, B B, thefront D is the draught-pole, which issecured, near its rear end, betwoentwo bars, E E, by a pin or bolt, (1.The rear end of the draught-pole is connected, by a pivot, b, with alever, F, which extends back underneath the driver's seat G, so that itmay be readily acted upon bythe feet of the driver; and, when said leveris depressed or forced down, the runners or furrow-openers C C, with thefront part of frame A, will be raised, (as shown in red in fig. 1,) inconsequence of the front end of the draught-pole being retained or heldby the neck-yoke of the team.

By this arrangement, the runners or furrow-openers, the ground with thegreatest facility.

On the frame A there are place both these'boxcs, over the bottomsthereof. v

This slide has two holes, 0 a, made through it at each end and theseholes, owing to a reciprocating motion which is given the slide, arebrought alternately in line with a hole, 0 in the bottom of each box,and underneath bars or cut-offs e, the seed in the holes a a beingdischarged when they come in line with the holes 01-. This mode,however, of discharging seed is old and well known, and does not requirea minute description..

The slide II is operated, or has a reciprocating motion given it, bymeans of clever, I, which has its fulcrumpin, atf, on the frame A, saidlever having a pin, g, passing vertically through it, which pin isfitted into'a groove, h, in the hub J of wheel 13, said grooved hubconstituting a care, which gives a vibrating motion to the lever i.

At any time when it is desired to render the seed-distributing deviceinoperative, the rear partvof the lover I is raised by means of a lever,K, which has a pin, 1', projecting from it at right angles, said barextending under the lever I. By simply raising the lever K, the pin 2'is made to press upward against the under side of luYOl' I, and raiseit, so that the pin g of I will be out of the groove h of the cam, and,consequently, no motion whenever required, may be raised from thesurface of communicated to the lover.

The roove 7t ma be curved so as to ive a reater or less number ofvibrations to the lover I at each a i g 9- revolution of the cam, inorder to drop the corn at a greater or less distance apart, as may bedesired; and, by closing one of the holes, a or c, at the ends of theslide I'I thC'll'Oppll'lgS of seed will be din1inishod,'of course,one-half, and the hills consequently planted at double the distanceapart.

Having this described my invention, I claim as new, and desire to secureby Letters Pate rit The foot-lever F, connected or applied to thedraught-pole I), to operate in the manner substantially as and for thepurpose set forth.

I AARON ARMSTRONG.
